Homework Statement
I am having trouble figuring out lambda for the 3x3, I have only done 2x2.
My matrix:
4 1 4
1 7 1
4 1 4
The Attempt at a Solution
I know that when I add lambda (L) in it looks like
4-L 1 4
1 7-L 1
4 1 4-L
When I do a 2x2, I would just cross multiply as my next step then solve for L values, but I don't know how to do that here. Any help would be appreciated!
